    Oligomeric Thioglycosides with α-d-manno-(1‘→2) Linkages from a Glycal-1,2-episulfide
    摘要:
    [GRAPHICS]Under basic conditions, phenyl 1,2-dithio-alpha-D-mannopyranoside farms a glycal-1,2-episulfide, which undergoes controlled oligomerization to afford a family of thio-oligo-alpha-D-mannopyranosides in a single reaction. The episulfide can also be intercepted by added thiolates, which leads to other sorts of thioglycosides. These alpha-(1-->2)- linked thio-mannopyranosides might have application as mimics of natural structures such as viral high mannose glycoproteins or ManLAM.

    摘要:
    吡喃糖苷 3, 4-顺式硫代碳酸酯在自由基促进的反应条件下(方法 A、B 或 C,如本文所述)以可接受的产率生成 O-S 重排产物,即顺式立体化学的 3, 4-硫醇碳酸酯。2在方法B(用六丁基二锡烷光解)中,反式立体化学的3-硫代碳酸酯也优先产生顺式立体化学的重排产物。尽管在大多数情况下产物的区域控制并不令人满意,但一些结果表明反应的区域选择性明显受到底物异头位置的立体化学的影响。通过常规方法将产物转化为硫代糖苷(全乙酸盐形式)。

  • Synthesis and binding affinity analysis of positional thiol analogs of mannopyranose for the elucidation of sulfur in different position
    作者:Bin Wu、Jiantao Ge、Bo Ren、Zhichao Pei、Hai Dong

    日期:2015.6
    serial inversion was successfully applied in the efficient synthesis of 2-thio- or 2,4-di-thio-mannoside derivatives. The protein recognition properties of the synthesized positional thiol analogs of mannose were then evaluated in a competition binding assay with the model lectin Concanavalin A (Con A), in order to investigate the roles of thiol group in the different position of the mannopyranose ring

  • A One-Pot Method for Removal of Thioacetyl Group via Desulfurization under Ultraviolet Light To Synthesize Deoxyglycosides
    作者:Jian-Tao Ge、Lang Zhou、Tao Luo、Jian Lv、Hai Dong
    DOI:10.1021/acs.orglett.9b02033
    日期:2019.8.2
    We herein developed an efficient method for removing thioacetyl to synthesize acylated deoxy glycosides in a one-pot reaction, where the thioacetyl was selectively deacetylated by hydrazine hydrate in DMF within 2-5 min at room temperature, followed by desulfurization under UV light for 1-2 h in the presence of TCEP center dot HCl. The method was then used to synthesize 2-deoxy glycosides with absolute alpha/beta-configuration via stereoselective control of C-2 thioacetate in glycosylation.
